ECA 100 is a light colored, low viscosity liquid epoxy curing agent designed for use in converting epoxy resins to highly crosslinked polymers with excellent physical and electrical properties. ECA 100 performs well when used in demanding applications, such as filament winding, pultrusion, and other forms of lamination, as well as electrical encapsulating, insulating, casting, and potting. ECA 100 imparts ease of handling due to low viscosity, low toxicity and low volatility. It is a mixture, which is a liquid at normal room temperature. If the product crystallizes, it should return to liquid by heating 38-55°C (100- 130°F) for 2-8 hours.

- Storage
ECA 100 will react with water to form diacids. This is normally undesirable, so ECA 100 should be stored in such a way that it is carefully protected from moisture contamination. For more details on the design of bulk storage for ECA 100, consult the Dixie Chemical Company brochure "Epoxy Curing Agent Storage Requirements."

- Formulation Example
ECA 100 was formulated with a variety of epoxy resins. Viscosity was measured at 25°C, and gel time was measured at 100°C. Samples were cured for 1 hour at 120°C, followed by a post-cure of 1 hour at 220°C, and glass transition temperatures were measured using a differential scanning calorimeter. The following table summarizes these results:
- Compatible Polymers and Resins
- Epoxies (EP)
- Electrical Performance Example
When a formulated with 100 parts BPA liquid epoxy resin, 78-82 parts ECA 100, and 1 part accelerator and then cured for 1 hour at 95°C, and 3 hours at 150°C, the following properties are found:
